LONDONDERRY – A former Transportation Security Administration employee at the Manchester-Boston Regional Airport is accused of possessing more than 1,000 child pornographic images on a laptop and thumb drive he had kept in his personal locker at the airport.

Miguel Angel Quinones, 38, of 67 Whittemore Ave., Manchester, turned himself into police Wednesday. He is being detained on $25,000 cash bail and is no longer employed by the TSA, police said.

The investigation began Jan. 2 when the Internet Crimes Against Children Task Force (ICAC) notified police that Quinones was being investigated for possessing child pornography.

Quinones voluntarily turned over his personal laptop and three USB thumb drives, which police said he kept in his personal employment locker at the airport, to ICAC investigators.

Londonderry police applied for a search warrant for the computer and thumb drives, while ICAC assisted with the forensic search once the warrants were approved.

On May 23, police received the results of that search which they said found more than 1,000 images and a video of what appeared to be child sexual abuse/pornography on the laptop and thumb drives, according to Londonderry police.
